摘要:

针对709份花椰菜自交系与骨干亲本,基于亲缘关系与22组农艺性状表型数据,筛选并构建了包含153个品系的核心种质资源集,占比21.58%。根据核心种质的表型变异数据,均值差异百分率为0、极差符合率大于80%以及较高的变异系数变化率等评价指标结果显示,构建的核心种质集的覆盖度与表型代表性良好。核心种质与全部种质之间的表型保留比分析、表型多样性指数t检验、不同性状均值t检验、主成分分析、插入缺失(Insertion/ Deletion,InDel)位点计数与分布统计等分析结果进一步验证了该核心种质资源的表型变异特征与遗传多样性,其能够有效代表709份花椰菜原始种质资源。

Abstract:

In the present study,709 inbred lines and backbone parents in cauliflower were resequenced,and their agronomic traits were analyzed. A core collection set containing 153 cauliflower lines was constructed based on the data of genotypes and 22 phenotypes. Furthermore,according to the data of phenotypic variation in these core collection,the results indicated that the percentage of mean difference was zero,the range coincidence rate was higher than 80%,and the variation rate of coefficient of variation was also commomly high. In addition,the analysis,such as phenotypic retention ratio,t test of phenotypic diversity index,t test of mean value of different traits,principal component and statistics of InDel locus counting and distribution,was carried out between the core collection and those original collection. The results confirmed that the core collection population largely represents the phenotypic and genetic diversity of the whole resource,which meets the requirements of core collection construction.

Key words: cauliflower, core collection, phenotypic trait, genetic diversity
